Microplastics in natural seafood of Vietnam and their potential exposure to consumers: A mini review
Summary
Researchers reviewed studies on microplastic contamination in seafood from Vietnam, finding plastic particles in 21 marine species including fish, shrimp, and shellfish, with fish carrying the highest loads. The findings highlight that consumers eating Vietnamese seafood regularly are ingesting microplastics, raising public health concerns about exposure through a major food source.
In this article, we review the occurrence and characteristics of microplastics (MP) in marine organisms used as food (seafood) from Vietnam and assess the consumers' health risks related to MP-contaminated seafood.Twenty-one marine species of fish, shrimp, and bivalves were reported to accumulate MP in their tissues, with the highest abundance in fish (Decapterus maruadsi, 87 items/individual) and the lowest abundance in hard clam (Meretrix lyrata, 0.25 items/individual).The mean values of MP abundance (items/g wet weight -ww) were 2.44, 0.73, and 0.85 in fish, shrimp, and bivalves, respectively.Fibre was the most common shape of MP, but fragment MPs were also observed in the tissues of marine organisms, and bead items were only found in shrimp.Various MP colours and more than ten MP polymers were noted in the seafood.The estimated
